I work with an email service provider and one of our senders is starting to see an increase in the amount of spam related bounces. Here is the bounce that is being returned:
550 5.1.0 OQtimc72yMwZU Sorry, we’ve identified a number of outgoing emails from your email provider as spam so we haven’t been able to send your email to its intended recipient. Please try again later or using an alternative email address. For more information visit our help article (link: help2.talktalk.co.uk/i-cant-send-or-receive-emails) (TT406)
Our client sends permission-based petition and social change type emails to subscribers who have signed up on their website to receive them. Our client follows best sending practices and does everything in their power to ensure that only permission-based email is being sent from their environment.
I tried to access the link in the bounce message, but it appears it is no longer active. Is there anyone I could work with to resolve this issue?

Hi Kent_Sparkpost, your PMs are enabled you should be able to send me a PM. I had others check and your PMs are showing enabled.

I've tried to send you a message, but I keep getting a 403 error. Are there any permissions that need to be set up on this account or is there an email address that I can send the IP and domain information?
Thanks again for your help,

Hi Kent_Sparkpost, please send me a personal message with the sender, recipient addresses and the date and time of sending. I'll then forward this over to mail team for investigation.

The mail service error message similar to '550 5.1.0 Outgoing emails identified as spam (TT406)' is telling you that TalkTalk Mail users have marked the received mail as spam. When many users mark mail as spam a permanent fail to deliver can get applied as in this example. Is just one sending address impacted or one outgoing server IP address impacted?
Unfortunately the explanation for TT406 hasn't had a redirect to the current help articles on Community. This issue isn't seen much because, as you agree, the mail service operators do all they can to avoid being marked as spammers.
When users don't unsubscribe but mark unwanted mail as spam or don't get promptly unsubscribed so mark unwanted mail as spam or when senders are sending to addresses that no longer exist, (TT506) error gets flagged up first, the sender is at risk of being blocked or rate limited.
Heads up that quite a few legacy email addresses are being deleted by TalkTalk because of non-use or because their users are no longer TalkTalk Consumer customers.
Keeping a cleaned distribution list promptly expunged of all failed bouncebacks is the objective.
